The CARES Act enacted last year allowed employers to defer payment of their 6.2% share of Social Security tax, otherwise required to be made from Mar 27, 2020, through Dec 31, 2020. Self-employed individuals could defer payment of a portion of their SECA tax owed for the same period.
Half of the deferred amount is due Dec 31, the other 50% on Dec 31, 2022.
You can make payments through the Electronic Federal Tax Payment System (EFTPS) or by check or credit card. Don’t send these payments in with other tax remittances.
If using EFTPS, there will be an option for employers to select deferral payments and for self-employeds to choose deferred Social Security tax.
If paying by check, be sure to make a notation on the check so that the payments are properly applied to your deferred payroll tax balance or to your deferred SECA tax balance.
